Application filed. December 2 '1 b all echo m. may concern:

Be it known th t 1 Moses F. llrloon', a citizen oi the luited States and a resident of New York. and State oi New York, have invented certain new and u ul l mprrwe neats in Poison Tablets. or which the s mcilication.

My invention relates to. poi. int-ablets and h: for its objectthe prijzduction of a tablet oi simple construction, oil? low cost to manufacture and designed primarily to render an accidental internal taking thereof impossible or an intentional internal taking of the poison very lilillicult.

ls'lcans for preventing the accidental swallowing; o'l poisons in tablet form, such as bichlorid of mercury, have long; been sought, and my invention contemplates the interlocking of the poisonous prepanition with a guard composed of a rigid material such as hard rubber or celluloid which shall be inert to the chemical action of the poisonous preparation used or to the solution resulting from the dissolvingo't" the poisonous preparation in a liquid.

To these ends my invention consists in the novel features and parts and combinations of the same hereinafter more particularly described and then specified in the claims.

In the drawings: Figure 1 is a plan View oi? the guard to which the poisonous preparation is molded and with which itis interloclied. Fig. 2 is a plan View of the poison tablet. Fig. 3 a side elevation of the same. Fig. 4 is a horizontal section of a.

form o'f'inold which may be used in the m anuilacture of the tablet. Fig. 5 is a transverse seotionof a modification of the tablet.

Like figures of reference indicate correspondingparts in all the views.

Referring; to the drawings and more particularly to Figs. 1 to Sincl'usive: 1 indicates a guard which may be of any suitable shape and which is provided With an open mg 2 at or near its center. The periphery or edge of the guard is serrated or provided with sharp points or prongs 3. The poisonous preparation l, as for instance bichlorid of mercury, is molded in its plastic state preferably to either face of the guard, passing through and completely filling the opening 2. The molded preparation 4 on either face of the guard may be of any suitable form or shape as for instance circular as" illustrated, but its circumference or area is Specification of Letters Patent.

in the county of New York irollouing is a 9,1913. aerial l lo. 609.172.

preferably greater than the circumference, or area of the opening 2 so that the desirable feature of havingthe poisonous preparation interlocl was. the guard is 'noduced. I

in Fig l.- l have shown a simple form oi mold ad..ptcd for use in the manufacture 9f my preferred term of tablet. T he lou'er mold-plate 8 is provided with a circular opening or hole l3 raring a shoulder whose depth equal to the thicl less of the guard 3 and on which the guard 3 rests as illustrated. The upper mold-plate 9 is also pro vided with a circular opening or hole adapted to register with the hole 13. The plastic poisonous preparation is then poured into the mold from either side or from both sides so that thropeuings 12 and 13 and the opening 2 in the guard 3 are completely filled, after which the plates ll) and ll are clamped to the nmld-plates and the poisonous 'ireparatiou is allowed to harden. Obviously the poisonous preparation 4-. is then. securely molded to and interlocked] with the guard 3.

In the modification shown in Fig. 5, the

guard 3 is provided with an openingaind has a collar 15 integrally uniteduith its edge, the upper and lower edges of the collar being serrated or prorided with prongs 6. The poisonous preparation 4 is then. molded to and interlocked with the guard 3 as in the former case. and a slightly different form of mold is used for its n'ianutacture as will be obvious.

The relatively large size of the guard and the sharp prongs or points with which it is provided make the accidental internal taking of the tablet impossible owing to the fact that the sharp prongs or points will instantly prick or hurt the person attempting to swallow the tablet, and any intentional taking of the poisonous preparation. would necessitate the cutting or tearing away of the same from the guard. Obviously the shape of the guard and also of the molded poisonous preparatio. may be varied Without departing from the spirit of my invention, but it is important that the guard be composed of some hard material Which is inert "to any undesirable chemical action of the poisonous preparation used. so that when the tablet is used by dissolving the same in Water the solution resulting therefrom Will not be rendered less eflicacious thanwould be the case if the use of the guard were not employed.

parting from the spirit of set forth in the appended claims: 7

' What I claim as my invention is 1. In a poison-tablet, the combination ofa guard having a serrated edge and a poisonous preparation securely fastened to said guard.

2. In a poison-tablet, the combination of a guard having a serrated edge and provided with an opening, and a poisonous preparation molded to and interlocked with said guard. A

3. In a poison-tablet, the combination of a guard'having its edge provided with prongs and a poisonous preparation securely .fas-

tened to the'guard, said guard consisting of a rigid substance inert to the chemical action of the poisonous preparation and to the solution resulting from the dissolving of the poisonous preparation in a liquid. 4. In a poison-tablet, the combination of a guard having a serrated edge, and a polsonous preparation molded thereto, said guard being composed of a rigid substance inert to the chemical action of the poisonous preparation and to the solution resulting from the dissolving of the poisonous prepa-- ration in a liquid. y

5. In a poison-tablet, the combination of a guard with an opening therein and having itsedge provided with prongs, and a poisonous preparation interlocked with said guard by molding the preparation through said opening and to the faces of said guard, said guardconsisting of a rigid material inert to the chemical action of the poisonous preparation and to the solution resulting from the dissolving of the poisonous preparation in a liquid.

6. In combination with a tablet or pellet containing pOLtJl'l, a guard carried by said tablet or pellet Which will prevent the swallowing of said tablet or pellet, said tablet or pellet being ofa size such thatit might be swallowed except for thetaction of said guard.

7.. In combination with a tablet or pellet containing poison, a guard carried by said tablet or pellet and having projecting means which will prevent the swallowing of said tabletor pellet, said tablet or pellet being of a size such that it might be swallowed except for the action of said guard.

8. A poisonous object and warning prongs mounted on and extending therefrom, por-- tions of the surface of said object being exposed.

9. A protector for a poisonous object comprising a body mounted upon the object, and warning prongs extending, from the body.

10. A poisonous antiseptic tablet and means thereon preventing the convenient swallowing ofsaid tablet, said means being associated with said tablet to permit of the ready dissolution of said tablet in a fluid' regardless of said means.
